After recovering from COVID-19 and having a tooth removed, why do I have a persistent blocked nose on that same side with thick mucus that is not responding to Moxikind CV, Sinarest, or Otravin, and what should I do?
Since your symptoms are on one side and haven't responded to amoxicillin/clavulanic acid (Moxikind CV), decongestants (Sinarest), or xylometazoline (Otrivin), it is possible the tooth extraction created a temporary connection to your sinus, causing localized sinusitis. Overusing xylometazoline can also worsen congestion. Please consult an ENT specialist and your dentist promptly. They may recommend an imaging study, like an X-ray or CT scan, to check your sinuses and healing tooth socket. In the meantime, gentle warm saline nasal rinses can help clear the thick mucus safely.
